WATER-CLOSET-FLUSHING-VALVE REGULATOR.

SPECIFICATION forming part of Letters Patent No. 514,110, dated February6, 1894.

Application filed February 2 3 l 8 9 2 To all whom/it may concern.-

Be it known that I, RUFUS WRIGHT, a citizen of the United States,residing at Akron,

in the county of Summit and State of Ohio, have invented a certain newand useful Improvement in Water-Oloset-Flushing-Valve Regulators, ofwhich the following is a specipreventing the Waste of water and, alsoretaining the elastic diaphragm in its normal shape, and preventing itfrom becoming hard.- ened in a distorted form from continued pressure.

To the aforesaid object my invention consists in the peculiar and novelconstruction, arrangement and combination of parts hereinafter describedand'then specifically pointed'out in the claims, reference being bad tothe accompanying drawings forming a part of this specification.

In the accompanying drawings in which similar reference numeralsindicate like parts in the diflerent figures: Figure 1, is a frontelevation of my invention; Fig. 2, a side ele-' vation of the same;Fig.3, a section of the same at the line 00, w, of Fig. 1, and Fig. 4, avertical central section of the base, the elastic diaphragm andimmediately connected parts hereinafter described.

Referring to these drawings, 1, is a supporting frame, ordinarily ofcast iron consist- .ing of two uprights provided with a base 2,

and two shelves 3, 4.

On the shelf 3, a plan of which is shown in Fig. 3, is mounted a bracket5, being a U shaped tube 6, having screw-threaded terminals 7, 8, forthe entrance and discharge of Water respectively and through the centerof the curve an opening guarded by a stuffing box 9, for the insertionand operation of a valve stem 10. The outer end of the terminal 7, isinternally cup-shaped and in it is a similar] y shaped valve 11, ofelastic material,

SerialNo. 422,536- (No model.)

as rubber, mounted on a rod 12, which extends into the inlet pipe and ispivotally connected with the outer end of a crank arm 13, mounted insideof said pipe on the valve stem 10, as shown in dotted lines in Fig. 1.

On the outer end of the stem 10, is a rocking bar 14, on which is asliding adjusting weight 15, held by a binding screw, the object ofwhich bar is hereinafter described.

On the base 2, and havingits edges clamped between the base and thelower ring of the frame 1 is a hollow, elastic diaphragm of rubber,hemispherical in shape having fastened in its center an air tube 17, onwhich is clamped bya screw-threaded nut 18, a metallic saucer-shapeddisk 19.

V In the shelves 3, and 4, are ways, in Fig. 3, in which is a verticallysliding bar 20, having at its lower end a cushion 21, of soft vulcanizedrubber, arranged to rest on and close the air tube 17. The lower end ofthe bar 20,

and the inner end of the bar 14, are connected by a link 22, so that thedescent and rise of the bar 20, will rock the bar 14, and open and closethe valve 11.

On the bar 20, above the shelf 4, is a sliding weight 23, which isgraduated to overcome its resistance of the weight 15, and elasticity ofthe diaphrgam 16, when raised and held against the bar 20.

In the front of the opening in the weight 23, in which the bar 20, fits,is a narrow front opening, indicated by dotted lines in Fig. 1, at aright angle with the main opening, in

which fits and slides a wedge shaped bar 24,

the lower end of which tapers to athin edge, and thence increases untilnearly the depth of the opening in the weight 23, where it is reduced by'a square shoulder forming alatch to engage the lower face of the weight23, and thence rising of the reduced size, is bent forward, and returnedbackward terminatingin a slightly inclined arm 26, the whole suspendedin a fulcrum 25, attached to the bar 20, and so adjusted that the weightof the arm overbalances the opposite part and constantly rocks the lowerpoint of the bar 24, outward, as shown in Fig. 2. The lower end of thebar 24, rests in an opening in the shelf 4, similar to, and invertical-adjustment with the opening in the weight-23, in which thelarger part of the wedge portion of the bar 24 rest. A handle 27, ofheavy wire passes through the weight 23, to which it is fastened byupper and lower nuts, the lower fitting in a recess and not shown, theends of which pass through the shelf 4, and are provided with nuts 28,to constitute stops for their upward movement.

When it is desired to flush the basin with which the apparatus isconnected, the weight 23, is raised by the handle 27, until it passesthe shoulder of the bar 24:, which swings under it thereby sustaining itwith bar 20, when the handle 27, is released. The weight 23, thussupported forces the bar 20, down, thereby compressing the diaphragm 16,its pressure thereon being gradually brought thereon by the disk 19, andthe air allowed to escape slowly through a small vent 29, in the nut 18,and it simultaneously rocks the lever 14, opening the valve 11. As thebar 20, continues to descend the lower end of the bar 24, is forcedinward by the opening in the shelf 4:, until as the weight 23, reachesthe shelf it is pushed so far inward as to release the weight 23, andpass through the orifice therein, and is immediately forced upward withthe bar 20, by force of the diaphragm 16, and weight 15, and restored toits normal position thereby rocking the lever 14, closing the valve 11,and having the weight 23, resting on the shelf at. The difierencebetween the weight of the bar 20, and the elastic upward force of thediaphragm 16, is regulated by moving the weight 15, on the lever 14, andto increase the force of the diaphragm 16, I inclose therein a coiledspring 30, as shown in Fig. 4.

On top of the bar 20, is a knob 31, by pressing on which the bar 20, maybe forced down, and the flushing valve operated, without using thehandle, weight or latch just described.

By the apparatus just described I accomand a rocking lever to open andclose it com-:

bined. with a vertically sliding bar arranged to rock said lever, anelastic diaphragm arranged to be compressed by said bar when it isforced down, and raise it when the force is removed, and a weight toforce said bar down and a latch to retain the weight on the bar duringits descent, and release it at the end of the downward stroke,substantially as shown and described.

2. In a flushing valve regulator, the valve and a rocking lever to openand close it, and a vertically sliding bar arranged to rock said leverand a detachable weight to force said bar down, and an elastic diaphragmarranged to be compressed by the bar in its descent, and raise it whenthe weight is releascd,c0mbined with an adjustable weight on saidrocking lever to regulate the resistance to the de scent of the bar andassist the diaphragm in raising it, substantially as shown and described.

In testimony that I claim the above I hereunto set my hand.
